Abstract

The utility model is a tree planting bag, which is characterized in that the tree planting bag takes a solid geometry shape and comprises two layers; wherein the outer layer is a brown paper (2), while the inner layer is a degradation plastic layer (1). The utility model is used for putting the sapling. Before degradation, the utility model can effectively isolate the sapling from the hills all around. And the biofertilizer, the slow released natural compound fertilizer and high efficiency water retaining agent are put in the utility model, and the water retaining agent can be thoroughly soaked with water to fully absorb the water till saturation; in this way, the water content in the water retaining agent can ensure the surviving, green returning and growth of the plants under the condition of no rain falling for two or three months. The utility model is simple in structure, convenient in transportation, simple and easy in operation and low in cost; and capable of naturally degradation in certain period, thus avoiding polluting environment.

Description

A kind of tree planting bag

Technical field

The utility model relates to a kind of tree planting bag that is used to plant trees.

Background technology

In order to preserve the ecological environment; improve the territory green percentage; country drops into substantial contribution and plants trees; every year, whole nation afforestation was all more than several 1,000,000,000 strains; but, the afforestation means support because falling behind shortage later stage pipe; the afforestation survival rate is lower; be lower than regional survival rate below the 600mm even be lower than 30% in annual rainfall; thereby the situation that causes afforestation every year not grow into forest; water that waters to plant when its reason is tree planting and the fertilizer of being executed; owing to link to each other with surrounding soil, moisture and nutrient are very fast by the surrounding soil loss, cause plant to lack moisture and nutrient and death.The country annual fund fall flat that drops into afforestation has caused a large amount of wastes of human and material resources, fund.

Summary of the invention

The purpose of this utility model provides a kind ofly can improve survival rate of plant, shorten the plant period of seedling establishment, is specifically designed to the tree planting bag of afforestation.

The technical solution of the utility model is: tree planting bag is a solid geometry shape, and bag is made of two-layer, and skin is brown paper (2), and internal layer is the degradable plastic bed of material (1).

The geometry of the utility model tree planting bag can be a square cylindricality, cylindrical, trapezoidal etc., and the size of tree planting bag is according to the difference of region, rainfall, plant roots and stems, and size respectively can be between 20～100 cubic centimetres.

Tree planting bag of the present utility model is that sapling is placed in the tree planting bag, before degraded tree planting bag can be effectively with sapling with massif is temporarily isolated on every side.In the bag bio-fertilizer, slow-release natural composite fertilizer and high-performance water-retaining agent are arranged, just can fully absorb water saturatedly as long as water permeable water-loss reducer when using, even 2～3 month not rainfalls, contained humidity also can be guaranteed surviving, turn green and growing of plant in the water-loss reducer.Simple in structure, the convenient transportation of tree planting bag of the present utility model, easy and simple to handle, cost is low, and tree planting bag will natural degradation in the regular period, can not pollute environment.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing, but be not limited to shown in the accompanying drawing.

Fig. 1 is a tree planting bag structural representation of the present utility model;

Fig. 2 is tree planting bag user mode figure of the present utility model.

Among the figure, the 1-degradable plastic bed of material, 2-brown paper, 3-melt pit, 4-bag with fertilizer.

Embodiment

As shown in Figure 1, tree planting bag of the present utility model is to be made of two-layer, and the skin of bag is a brown paper, internal layer is the degradable plastic bed of material, internal layer combines firmly with outer brown paper with the method for coating, and tree planting bag is the solid geometry shape, can adopt square column type (or cylindrical, trapezoidal etc.).

In the use, as long as according to the operation sequence operation, disposable watering, it is saturated that a bag interior water-loss reducer is fully absorbed water, and can reach more than 80% at common regional survival rate of planting, can be increased to more than 90% in district's survival rate more than precipitation 800mm.

Claims

1, a kind of tree planting bag is characterized in that tree planting bag is a solid geometry shape, and bag is made of two-layer, and skin is brown paper (2), and internal layer is the degradable plastic bed of material (1).
